Matthew Lewis, aka Neville Longbottom from Harry Potter (who, by the way, is freakin' HOT nowadays) joins Chris Stark and Scott Mills on BBC Radio 1 for a game of Innuendo Bingo.

Basically, they fill their mouths with water while Scott plays out a load of downright hilarious audio clips and the challenge is not to let the water explode from their mouths. They don't do very well, spraying water out on the first thing they hear.

On a sidenote, you may remember Chris Stark from his junket interviews in which he pretends to be a quivering mess of nerves. Well he's pretty damn cool and collected here, isn't he? Hmmm *squints eyes*. I'm on to you, Chris.
